Eat fish, Live longer

Older adults who have higher blood levels of omega-3 fatty acids -- found in fatty fish and seafood -- may be able to lower their overall mortality risk by as much as 27% and their mortality risk from heart disease by about 35%, according to a new study from Harvard School of Public Health (HSPH) and the University of Washington. Researchers found that older adults who had the highest blood levels of the fatty acids found in fish lived, on average, 2.2 years longer than those with lower levels.

Overall, study participants with the highest levels of all three types of fatty acids had a 27% lower risk of total mortality due to all causes.
